Allowable Load per Area for Cast Iron Columns Solution

STEP 0: Pre-Calculation Summary

Formula Used

Allowable Load = (12000-(60*Slenderness Ratio))*Section Area of Column
Q = (12000-(60*λ))*A
This formula uses 3 Variables

Variables Used

Allowable Load - (Measured in Newton) - The Allowable Load is the maximum working load that can be applied on the structure.
Slenderness Ratio - Slenderness Ratio is the ratio of the length of a column and the least radius of gyration of its cross section.
Section Area of Column - (Measured in Square Meter) - The Section Area of Column is the area of a two-dimensional shape that is obtained when a three-dimensional shape is sliced perpendicular to some specified axis at a point.

STEP 1: Convert Input(s) to Base Unit

Slenderness Ratio: 0.5 --> No Conversion Required
Section Area of Column: 52900 Square Millimeter --> 0.0529 Square Meter (Check conversion here)

Allowable Load per Area for Cast Iron Columns Formula

Allowable Load = (12000-(60*Slenderness Ratio))*Section Area of Column
Q = (12000-(60*λ))*A

What is the difference between Ultimate Load and Allowable Load?

Under the Allowable Stress Design (ASD) method, the allowable load is based on the application of a safety factor to the mean result of laboratory testing to failure, regardless of the controlling failure mode observed in the tests.
the ultimate load is a statistical figure used in calculations and should (hopefully) never actually occur.
Strength requirements are specified in terms of limit loads (the maximum loads to be expected in service) and ultimate loads (limit loads multiplied by prescribed factors of safety).

Define Slenderness Ratio and it's purpose.

It is defined as the effective length of the column and the least radius of gyration, the latter defined by the area of the cross-section of the column and is the second moment of the area of the cross-section.
It is used extensively for finding out the design load as well as in classifying various columns in short/intermediate/long. The slenderness ratio of a column gives an indication of buckling failure in the column. The more the slenderness ratio, more the tendency of a column to fail by buckling effect in that direction.
